java错误：类型登录不是对象控制器的成员。应用程序（播放框架）
我正在用IntelliJ在Play FrameWork上与ZenTask (JavaGuided)一起练习。我完全按照概述的步骤进行了操作，但我不断遇到这个恼人的错误：
"Type Login is not a member of Object controller.Application".
请帮助识别错误。我发现这个框架非常有缺陷，令人沮丧
完整错误消息：
Error:(24, 196) type Login is not a member of object controllers.Application
class login extends BaseScalaTemplate[play.twirl.api.HtmlFormat.Appendable,Format[play.twirl.api.HtmlFormat.Appendable]](play.twirl.api.HtmlFormat) with play.twirl.api.Template1[Form[Application.Login],play.twirl.api.HtmlFormat.Appendable] {
Error:(27, 43) type Login is not a member of object controllers.Application
def apply/*1.2*/(form: Form[Application.Login]):play.twirl.api.HtmlFormat.Appendable = {
Error:(71, 36) type Login is not a member of object controllers.Application
def render(form:Form[Application.Login]): play.twirl.api.HtmlFormat.Appendable = apply(form)
Error:(73, 28) type Login is not a member of object controllers.Application
def f:((Form[Application.Login]) => play.twirl.api.HtmlFormat.Appendable) = (form) => apply(form)
这是我的代码：
package models;
import com.avaje.ebean.Model;
import javax.persistence.Entity;
import javax.persistence.Id;
@Entity
public class User extends Model {
@Id
public String email;
public String name;
public String password;
public User(String email, String name, String password) {
this.email = email;
this.name = name;
this.password = password;
}
public Finder<String,User> find = new Finder<String,User>(
String.class, User.class
);
public User authenticate(String email, String password) {
return find.where().eq("email", email)
.eq("password", password).findUnique();
}
}
控制器：form和loginForm在render(form(Login.class)))和render(loginForm))中突出显示为错误：
package controllers;
import models.User;
import play.data.Form;
import play.mvc.Controller;
import play.mvc.Result;
import views.html.index;
import views.html.login;
public class Application extends Controller {
public Result index() {
return ok(index.render("hello"));
}
public Result login() {
return ok(login.render(form(Login.class)));
}
public Result authenticate() {
Form<User> loginForm = Form.form(User.class).bindFromRequest();
if (loginForm.hasErrors()) {
return badRequest(login.render(loginForm));
} else {
session().clear();
session("email", loginForm.get().email);
return redirect(
routes.Application.index()
);
}
}
public class Login {
public String email;
public String password;
public User user;
public String validate() {
user.authenticate(email, password);
if (user == null) {
return "Invalid user or password";
}
return null;
}
}
}
视图：登录突出显示为错误
